Engineering Selection Recommendations
Direct Equivalent (RoHS3 Compliant, Matching Specifications):
110-87-314-41-001101 (Preci-Dip) provides the closest functional match to ICA-314-SGG. Both parts maintain identical mechanical dimensions, 14-position configuration, 0.3" row spacing, and 0.100" pitch. Both are RoHS3 compliant and rated for -55°C to 125°C operation. The primary difference is the post contact finish (tin vs. gold) and mating contact finish thickness (flash vs. 30.0µin plating). This part is suitable for direct substitution in applications where post finish material is not a critical constraint.
Higher Current Rating Alternatives (RoHS3 Compliant):
110-13-314-41-001000 and 110-13-314-41-801000 (Mill-Max) both provide 3 A current rating versus the 1 A rating of ICA-314-SGG. These parts maintain identical mechanical compatibility and RoHS3 compliance. The reduced post contact finish thickness (10.0µin gold) represents the primary specification variance. These parts are suitable for applications requiring higher current capacity while maintaining the same form factor.
110-43-314-41-605000 (Mill-Max) combines 3 A current rating with specified 10 mOhm contact resistance, matching the contact resistance specification of ICA-314-SGG. This part is suitable for applications where contact resistance specification is a design requirement.
Alternative Contact Finish Options (RoHS3 Compliant):
110-41-314-41-001000, 110-43-314-41-001000, and 110-43-314-41-801000 (Mill-Max) provide tin post finish with 3 A current rating. These parts maintain mechanical compatibility and RoHS3 compliance. Selection depends on post finish material compatibility with the application's solder process and environmental requirements.
110-44-314-41-001000 (Mill-Max) features tin mating contact finish with 3 A current rating. This part is suitable for applications where tin contact finish is preferred over gold.
Non-RoHS3 Compliant Alternatives:
110-91-314-41-001000 and 110-93-314-41-001000 (Mill-Max) feature tin-lead post finish and are RoHS non-compliant. These parts are suitable only for applications where RoHS compliance is not required and tin-lead termination is acceptable.
Frequently Asked Questions (FAQ)
Q: Can 110-13-314-41-001000 replace ICA-314-SGG in all applications?
A: 110-13-314-41-001000 is mechanically and electrically compatible with ICA-314-SGG for DIP socket applications. The primary differences are the 3 A current rating (versus 1 A) and reduced post contact finish thickness (10.0µin gold versus 30.0µin gold). If the application requires only 1 A maximum current and specifies 30.0µin post finish thickness, verify that the thinner finish meets your design requirements before substitution.
Q: What is the difference between gold and tin post finishes?
A: Post finish material affects solder wetting characteristics and long-term reliability in different environmental conditions. Gold provides superior corrosion resistance and is preferred for high-reliability applications. Tin offers cost advantages and is suitable for standard commercial applications. Selection depends on your specific solder process compatibility and environmental exposure requirements.
Q: Is 110-87-314-41-001101 (Preci-Dip) a direct equivalent to ICA-314-SGG?
A: 110-87-314-41-001101 maintains identical mechanical dimensions, position count, pitch, and operating temperature range as ICA-314-SGG. Both are RoHS3 compliant. The mating contact finish differs (flash gold versus 30.0µin plating) and the post finish is tin instead of gold. For applications where these finish specifications are not critical design parameters, this part provides direct functional substitution.
Q: Why do some substitute parts have 3 A current rating instead of 1 A?
A: Higher current rating indicates the part can safely conduct greater current without exceeding temperature rise limits. A 3 A rated part can be used in applications requiring 1 A or less without derating. The higher rating does not affect mechanical compatibility or form factor.
Q: Are RoHS non-compliant parts (110-91-314-41-001000, 110-93-314-41-001000) suitable substitutes?
A: RoHS non-compliant parts are suitable only for applications where RoHS compliance is not a regulatory or design requirement. These parts feature tin-lead post finish, which is restricted in RoHS3 compliant designs. Verify your application's compliance requirements before selecting these alternatives.
Q: What does contact finish thickness (measured in µin) indicate?
A: Contact finish thickness specifies the plating layer depth on mating or post contacts. Thicker plating (30.0µin versus 10.0µin) provides extended contact life and improved corrosion resistance in high-cycle mating applications. For static or low-cycle applications, thinner finishes are acceptable. Verify your application's mating cycle requirements when selecting between parts with different finish thicknesses.
Q: Can I substitute a part with unspecified contact resistance for one with 10 mOhm specified?
A: Contact resistance specification indicates a guaranteed maximum value. Parts with unspecified contact resistance may have equivalent or higher actual resistance. If your application requires a maximum contact resistance limit, select only parts with specified 10 mOhm or lower values. 110-43-314-41-605000 explicitly specifies 10 mOhm contact resistance.
